PIPE-CLEANER.

SPECIFICATION formingpart of Letters Patent No. 226,740, dated April 20,1 880.

Application filed December 30, 1879.

.To all whom it may concern:

Be it known that I, JOHN H. GABLE, of

Sharnokin, Northumberland county, State of Pennsylvania, have invented anew and useful Improvement in Pipe-Cleaners, of which the following is aspecification. v Figure 1 is a side elevation, partly in section, of theimprovement. Fig.2 is a cross-section taken onthe lines: 00, Fig. 1; andFig.3 is a crosssection taken through the line 3 3 Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish pipe-cleaners for cleaningdeposits of sediment from the inner surfaces of the column or pump Ipipes of mine shafts and slopes, and for cleaning out other pipes.

The invention consists of a pipe cleaner formed of a cylinder or frameprovided with cutters to loosen the sediment, wheels to crush andpulverize the said sediment, and a brush to sweep the inner surface ofthe pipe, as will be hereinafter fully described.

A represents a section of a column or pump pipe. B is a hollow cylinderor frame, of less diameter than the pipe A to be cleaned, so that it maymove up and down through the said pipe A freely.

To the upper end of the cylinder or frame B is attached a cross-rod, O,to which is attached the end of a chain or rope, D, for raising andlowering the cleaner.

E are the wheels, which may be made solid or skeleton, and are pivotedto rods F, attached to the cylinder'or frame B.

The wheels E are made of a greater diameter than the cylinder or frameB, so as to project through slots in the sides of the said cylinder orframe B, to bear against the inner surface of the pipe Ato crush andpulverize the loosened sediment, so that it will be carried out by thewater passing through the said pipe A.

The wheels E are arranged at angles with each other, as shown in Figs. 1and 3, so as to bear against all sides of the pipe A.

The lower end of the cylinder or frame B is slotted to form chisels orcutters G, or has chisels or cutters Gr attached to it, as shown in Fig.1.

.The ends of the cutters G are beveled upon the inner sides to formchisel points or edges, to separate the sediment from the inner surfaceof the pipe A, so that it may be ground and pulverized by the wheels E.

To the ends of the cylinder or frame B is attached a wire brush, H, tosweep and brush off the inner surface of the pipe A as the cleaner movesup and down.

In using the cleaner itis inserted in the end of the pipe A withoutstopping the pump, and loosens, crushes, and pulverizes the sediment, sothat it will be carried out by the water.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. A pipe-cleaner constructed substantially as hereinshown and described, consisting of the cylinder or frame B, the wheelsE, the cutters G, and the brush H, as set forth.

2. In a pipe-cleaner, the series of wheels E, piy'oted within andprojecting through a cylinder, B, placed successively one above anotherand at an angle to each other, to form a crusher, as described.

3. The cylinder B, provided with cuttingedges G and wheels E,substantially as and for the purpose specified.

4. The cylinder B, provided with the wheels E and brush H, substantiallyas and for the purpose set forth.
